It may be possible to rewire your brain so that it wants — craves, even — healthier foods.
Previous studies have shown that high-calorie, fatty, sugary foods trigger the pleasure center of the brain. That’s why you naturally crave these unhealthy foods: You expect to be rewarded with dopamine for eating them.
But people in the experimental group showed a slightly different response to seeing high-calorie foods after participating in the intervention program. Researchers saw less activity in the stratum when participants were shown these foods and more activity when they were shown lower-calorie foods.
The sample size is incredibly small.
